Calopadia saxicola is a species of saxicolous (rock-dwelling) crustose lichen in the family Ectolechiaceae. It is found on the rocky shores of southern Brazil, where it thrives in the shade of vegetated zones and grows directly on rocks away from other crustose lichens. The lichen was formally described as a new species in 2015. Calopadia saxicola stands out from its close relatives due to its well-defined thallus, reddish-brown disc, thicker hymenium, and smaller conidia.
Calopadia saxicola was first described by Emerson Luiz Gumboski in 2015. The type specimen was discovered in Brazil, within the state of Santa Catarina, in the Municipality of Penha, on the rocky seashore just north of Praia Vermelha. The species epithet alludes to its rock-dwelling habitat preference.[1]
Description
The saxicolous thallus of Calopadia saxicola is continuous and clearly defined, with colours ranging from whitish to pale brown, and dirty brown on older parts. It has a smooth to rugose surface, a weakly shiny appearance, and can be up to 0.3 mm thick and 10 cm (4 in) in diameter. The lichen's apothecia are biatorine and sessile, with a brownish to reddish-brown disc covered in whitish pruina, while the asci are mainly 2–3-spored. The conidia are filiform, curved with a single smooth clavate apex, and hyaline, typically measuring 45–55 by 2.0–3.5 μm, with 4–7 septa. The lichen does not contain any detectable secondary metabolites.[1]
